Garage Door Springs in Torrance: Torsion vs. Extension (And When Yours Snaps)
2026-09-01 7 min read
A snapped garage door spring won't let your door budge, and most homeowners don't know whether they have a torsion or extension spring sitting above their head. Here's the truth: torsion springs sit horizontally above the door and handle almost all the weight. Extension springs run along the sides and only kick in when the door moves. Both fail eventually. The difference matters when you need a same-day repair in Torrance.
How Garage Door Springs Actually Work
Your garage door weighs between 300 and 500 pounds. Without springs, your opener would burn out in weeks trying to lift that load. Springs store and release energy, making the door feel weightless when you press the button.
Torsion springs are the heavy lifters. They twist as your door opens and closes, distributing force evenly across the entire door. You'll find one or two mounted on a metal rod above the center of the doorway. Extension springs do the same job differently, stretching and contracting along the top corners of your door frame. Most newer homes use torsion springs because they're safer and last longer, typically 7 to 9 years with normal use.
When a spring snaps, you'll hear a loud bang. Don't try to open the door manually afterward. A broken spring removes all counterbalance, and the door becomes a 400-pound hazard.
Why Springs Break (And When You Need a Repair)
Springs fail from metal fatigue. Every open and close cycle puts stress on the coils. A spring rated for 10,000 cycles will eventually give out. Some homeowners get 15 years. Others see failure at year five. It depends on how often you open and close that door.
Rust accelerates failure, especially near the coast. Torrance sits just miles from the Pacific, and salt air corrodes springs faster than inland areas like Pasadena. If your spring looks orange or flakes off when you touch it, corrosion is eating away at your metal. Lack of lubrication also shortens spring life. Check our guide on garage door lubrication in Torrance to learn when and how to maintain them.
Temperature swings matter too. Cold mornings make metal contract. Hot afternoons expand it. Over years, this cycling weakens the material. You can't prevent this, but you can spot warning signs early.

Torsion vs. Extension: Which Do You Have?
Stand inside your garage and look up. If you see a thick metal rod running horizontally above the door with a spring coiled around it, you have a torsion system. If the springs run vertically along the sides of the door frame, you have extension springs.
Torsion springs cost more to replace but are safer and more durable. Extension springs are cheaper upfront but wear out faster and pose a pinching hazard. Both require professional replacement. Never attempt this yourself. A snapped spring under tension can cause serious injury.

What Causes a Snapped Spring (Beyond Age)
Sudden temperature drops can snap a weakened spring. A morning in the 40s after weeks of heat puts stress on old metal. Rust weakens the coil structure. One hard cycle, and it gives.
Poor maintenance accelerates failure. Springs that never get lubricated wear faster. Dust and debris accumulate in the coils, trapping moisture. Humidity near the coast makes this worse.
Overuse stresses springs too. If your door opens and closes 20 times a day for a business, springs fail earlier than residential use. We serve commercial clients across Torrance with heavy-duty solutions designed for high-cycle doors.
